HELP!! Half-Bricked Phone

I did something stupid and installed rom manager, it corrupted my recovery. I restored to stock rom i found online using odin but it says you need to wipe factory settings to make it boot. The recovery is now the stock one but it displays error messages and when I choosed a command it does nothing. What should I do?
EDIT: I flashed another stock rom this time i could boot into the phone. Some of my apps went missing and superuser went missing. It was a little weird. The recovery still shows errors and no command. It says
"can't access to '/system/csc/VAU/system". I don't think I can root it again and install a custom rom. I dont know what is the right thing to do now. I just want to root it and install a rom
EDIT2: I installed another recovery called Amon-RA recovery and I still get errors. I am thinking maybe the recovery partition is corrupted. I get these errors.
E: Can't mount CACHE:recovery/command
E: Can't mount /dev/block/stl14

E: Can't mount CACHE:recovery/log

Hmmm. I'd just restore back to stock again, but using getting the stock images and running the .bat file.
Then install CWM again and try..
http://sbf.droid-developers.org/phone.php?device=14
Choose the right version, and unzip, then put the phone in download mode and run the .bat
(If you are on Android 4.4, then I would recommend you stay on 4.4, but if you are on 4.3, stay on 4.3)
Good luck!

Cannot install custom rom (5.1)

Hi!
I have a big problem.. I spent whole day, and I can't resolve it.
Im trying to install this ROM: http://forum.xda-developers.com/moto-g/development/rom-minimal-os-moto-g-2013-t3154972
Only way to run 5.1 is this app: http://forum.xda-developers.com/moto-g/general/gpe-lollipop-5-1-1click-installer-t3075522
After fresh install of 5.1 im rebooting to recovery (newest twrp, also I had newest bootloader), and flashing minimal os zip...
Then I got:
"E: Error executing updater binary in zip '/sdcard/MinimalOS-v3.0-OFFICIAL-20151005-falcon.zip'
Error flashing zip 'sdcard/MinimalOS-v3.0-OFFICIAL-20151005-falcon.zip'
Updating partition details...
E: Unable to mount '/system'
...done"
Ofc. before flashing /system is mounted and working (im able to run Lolipop)... What can I do? Flashing with CWM also isn't succesful...
Please, please help me...

İ either to facing this problem then i solve this way
But then, when i try install custom rom like cm12.1 does not progress. İt is stuck patching system image unconditionly
İ can not solve this problem

Google Pixel (sailfish) TWRP install not working - failed to mount /system_root and /vendor

Hey all!
I've been trying to install TWRP on my google pixel (32 GB/ 4GB). It runs Android 10, has an encrypted filesystem and the boot loader is unlocked. I booted into fastboot mode, then used fastboot boot twrp.img to boot into TWRP and it worked perfectly fine. Then, after decrypting, I tried flashing the TWRP zip I had on my phone. But it failed to do so, giving these errors - Failed to mount /system_root (invalid argument); Failed to mount /vendor (invalid argument). When I checked the mounted partitions in TWRP, system and vendor were unchecked and I couldn't check them.
Next, I tried to use fastboot flash recovery to flash the TWRP image directly from fastboot but this didn't work either.
Finally, I tried to flash a TWRP image after booting to TWRP. I chose the install to recovery ramdisk option but it didn't install, giving me the same failed to mount errors.
So right now I'm stuck at this point. Any help will be really appreciated
Thanks

You should indicate which image you are booting and flashing. There are several and from what I gather, not all are compatible with 10.

Try 3.3.0 instead (for both). The last I can find on my records that I used is 3.1.0.
Edit:
fastboot boot image
Flash twrp zip
Flash magisk zip
Reboot
Should be rooted with twrp installed.
This is how it used to work at least.
Okay I will try that out thank you!

Hey! I tried what you said, booted into twrp using fastboot. But when I entered my password to decrypt data it says "password failed, please try again". This did not happen when I used the other img.

I read through the twrp thread. I don't think they ever got deception working on 10. Not by installing, just booting.

I don't think you can on Android 10. You can try but I think people just booted twrp when they wanted to use it.
I think I'm having the same problem or at least a very similar one, I get the same errors in TWRP (started with ""fastboot boot twrp.img") saying unable to mount /system_root and /vendor but i am still told installation was successful anyway. Unfortunately, when I reboot to recovery, it seems to try and start TWRP but the phone restarts after the google boot logo and this will happen every time.
You can get the older verson of (temporary) TWRP Tulsadiver suggested using past the decrypting stage simply by removing your password/pin in settings > security > screen lock but using this version didn't help me at all.
I have tried going back to an earlier stock rom using google's images and trying to install TWRP again but this didn't work either.
Please let me know if you get anywhere with this.
I also have the same problem. It just saying unable to mount /system_root (Invalid argument)
And the /system is read-only,
I need to modify the files on /system partition, what should I do?
I've tried 3.4.0.0 and 3.3.0.0 and 3.6.9.0-9-0 but all failed.
Thank you all!

Any idea how to install TWRP on Pixel with Android 10?

Failed to mount '/system_root' (invalid argument). Failed to mount '/vendor' (invalid argument). Failed to mount '/product' (invalid argument)

thanks guys
i really need some help guys
I had the same thing this weekend trying to fix an issue i had. What helped with me is putting the image on an external SD card and flash from there.
When I saved the custom rom on the phone storage and flashed it from there, same failed to mount errors.
I have no idea why either, but worth a try maybe? My guess its something with the internal storage.
My procedure was:
Recovery - wipe dalvik and cache - format data - connect to PC, transfer FW and custom rom - flash FW: Succes - flash WaveOS: failed to mount. Reboot recovery - try to install, but WaveOS not on internal storage (empty). Connected to PC - transferred rom - install from internal - mount error. Reboot, again no image file on internal.
Afterwards transferred ROM to sdcard, selected it with install from storage; succes.

thats really strange for me , beacuse i have the same issue , but in order to fix it somone say it need update twrp , or the rom u try to install is no vendor
but its actually true that something broken in twrp that can't read/write internal before we finish wipe data,cache,dalvik
so that give error becus all system,vendor,product missing/can't read by twrp BUGGY,
so instead update my twrp i just flash stock rom and try again,
but this time i use OrangeFox
without FW flash And only flash rom corvus 16.7
success and format data > Yes > reboot.
there you go its success but the rom looks like buggy and its real bug or maybe i don't install FW before the rom? can u pls answer this << ? thanks.
so if u guys(all who got this error) still can in twrp and UBL u can just flash stock rom via Miui Flash / update twrp
really strange error for me

my phone now bootloop on fastboot
https://forum.xda-developers.com/t/poco-x3-nfc-bootloop-fastboot.4365899/
Hello guys, I installed Pixel experience custom on my poco x3 a few weeks ago. After few days, I tried to update the PE custom from but it showed failed "error 1" so, I skipped and forget about the update and kept using the phone.
Yesterday, I decided to go back one MIUI. I downloaded MIUI for my POCO X3 EEA version. I couldn't install it too, as it always showed "error 1". and starting yesterday, the phone bootlooped in fastboot.
Today, I tried to install the Official Miui Rom using MiFlashtool but always the same issue. First I tried installing the global official rom, it didn't work, then, installing EEA version but same thing.
Someone here can help me on that matter please, I never get an idea in how to fix that issue.
Thank you so much in advance for your help

ur phone is still UBL or not? its really ez to flash via miflash if u dont have any problem with UBL, because if ur phone ubl u cannot do nothing except u flash it with EDL 9008 < this is what i read atleast
but for me personally its still always a hope , can u do another stock rom miui? try INDIA / INDONESIA / GLOBAL
HIGHLY RECOMEND IS GLOBAL / INDONESIA < BEST STABLE FOR NOW
the reason u update PE rom is what? did u install a dirty / clean flash? cuz no way u can calm and relax with dirty flash, ur emmc will be sad
pls note try another stock rom install via miflash < safest way without breaking
read carefully step by step
find solution for ur error 1
